It all started at the age of seven when I and my family were on a trip to Delhi throughout the trip the breath of mine was heavy. At that young age, I couldn’t figure out what was happening, but soon when Delhi was declared as the most polluted city on earth, I realized what happened to me at that time. This incident developed my keen interest in solving the problem of different types of pollution. The fact that Delhi now is the most polluted city on earth, it urgently needs a solution. On November 8, 2017, at 8 PM, the air quality index of the city Delhi went up to 1,010 per cubic meter, Explaining that single breath of Delhi is similar to you smoking over 50 cigarettes. The toxic chemical on November made smog and choked 19 million innocent lives of the metropolitan area. Each hospital reported a 20% surge in patients with the pollution-related illness. Most air pollution is caused by the effluents released by, factories and vehicles. One simple solution is the separation of the pollutants either physically, biologically or chemically which is not feasible. During research, I found out that chemicals that absorb pollutants are present in clay pots. I have contextualized a very cheap filter that is made out of old broken clay pots, later these absorbed pollutants could be, either converted into bricks and are utilized or could be reused by drying the absorbed and dusting the pollutants off causing no harm to the environment. These biodegradable filters could be put on chimneys and other polluting endings of various industries and vehicles. And later could be utilized as bricks.
The Indian capital,Delhi is currently suffering with an incurable but reducible problem of diffrent types of pollution. It was November 8th at 8 PM the air quality index went up to 1,010 per cubic meter explaining the fact that one breath will be equal to smoking 100 cigarettes. The toxic chemical on November made smog and choked 19 million innocent lives of the metropolitan area. Each hospital reported 20% surge of patients with pollution related illness. Currently there has been no solution to this problem except for reducing it but not eradicating it.
During my research I found out that old broken pots contain chemicals that absorb high quantities of pollutants in them.After the absorption of the pollutants we could utilize them to make strong bricks or could be reused by drying the absorbed and dusting the pollutants off and disposing them in a proper maner causing no harm to the environment.
Is it possible to create a low cost pollutant absorbent which after the utilization could be converted into bricks for further use?
An extremely cheap and easy way of eradicating pollution utilizing old broken pots.It is a simple filter that could be used in air to reduce it.After the utilization of this filter the absorbent could be converted into bricks and cold be used to make houses and building or or could be reused by drying the absorbed and dusting the pollutants off and disposing them in proper manner causing no harm to the environment.
There are some amazing researchers and solution towards the problem of pollution and each of these solutions are mind-blowing but, the fact that these filters were developed in research centers the product is not feasible, not just that but these filters require more resources and highly skilled labors to produce in large scale. Most chemicals used in filters today make use of activated charcoal and this charcoal is made by polluting methods.
In the past researches I found out the main basic chemicals that cause most of the pollution and they are Particulate matter (PM) and carbon dioxide. The chemicals that absorb these pollutants are present in most clay pots.since clay pots are vital in most of the Indians life at times when these get old and get cracked they become unusable since these pots are cooked well before usage these do not break that easily , plastic sacks which itself is a pollutant, it is unusable after a couple of times and is thrown in open areas these are non-biodegradable, hence due to improper disposal cause choking of pipelines and hazard to the environment.
Today the simple solutions to clear different pollutions are either physical by hand picking, biological by controlling microbial growth and lastly chemically by using synthetic chemicals that absorb the pollution.
Through the study on this topic, I sought to create a simple filter that absorbs most of the pollutants in the environment and filters the required. This filter is highly eco-friendly as and when after the absorption of the pollutants the filter could be converted into a brick causing no harm to the environment. I made use of the broken clay pots that purify the water and make it drinkable and this filter can also be used in several other poolluting endings like the one in vehicles
Experimental conditions -
All the experiments were carried out in school chemistry laboratory with an atmospheric temperature of 31oC.
Reason to take polluted water and not air-
Water was taken under consideration as it’s a highly versatile substance and any pollutant could be dissolved in it easily whereas, on the other hand, it would be difficult for us to test the gas filtered after the filtration. It would be really easy for us to get the results as the gas produced after filtration cannot easily test, as liquids are highly versatile and anything could be added and could be discharged from them.
1) Purification of polluted water
This experiment is carried out to check the presence of pollutants in the water after filtration from the filter created. A fake polluted liquid was made under the supervision of my mentor with few chemicals resembling the polluted air and was passed through the filter made. Particular amounts of chemicals were added to the liquid to make it resembling the polluted air, the amounts of which are stated below-
Once these chemicals were dissolved well the liquid with the help of a beaker was passed through the simple filter created the liquid passed through several layers of pollutant purifiers and the liquid that was obtained below was collected in a beaker again and was tested.
2) Testing of water obtained after filtration
The liquid obtained after filtration was tested in this experiment, to get the outcome/result of the experiment performed. The liquid was put in 5 different Petri dishes each containing 2 ml of the filtered liquid. The liquid was further examined in the KV RWF chemistry laboratory under the supervision of my mentor.
For the testing of the presence of carbon dioxide(CO2) the liquid without filtration was added to the lime water and the liquid after filtration was added to the lime water to compare the two, later the readings were noted down.
The utilization of the microscope was done to check the presence of particulate matter and the readings were noted down.
3)Test on plants with filtered water
Plants are the only living organism which shows similar reactions to that of humans and the real environment, Hence this experiment was performed. There were 2 planting containers taken one as "Control" and the other as "filtered water". In "control" was only put polluted water every day in the plant "filtered water" 100 ml of the water obtained after filtration was put under the following plant parameters.
|Parameter||day 0||day 10||day 20||day 30|
|2)Height of plant|
|3)Thickness of leaf|
|4)Area of leaf|
|5)number of leaves|
|7)Number of flowers|
|9) Root mass(only last reading)|
4)Real life application
This project is not just a prototype. I performed a real-life application on the exhaust pipe of a car. The filter was made fixable to the pipe with the help of a technician and was put to test.
From the experiments performed and data collected the following are the results that concluded my project.The following is the picture of the carbon that was obtained by Clay pots.
1) Purification of polluted water
After the purification of the polluted liquid was done by passing it through the
2) Testing of water obtained after filtration
Pollutants Presence :-
Particulate matter 0.06%
carbon dioxide 2%
Volatile organic compounds 0.1%
Polycyclic aromatic hydrocarbons 0.9%
Testing of each chemical was done by making use of chemicals that show their presence. The percentage of each of these chemicals are a lot less than the normal drinking water that we drink each and every day. Hence it's not just cheap but also better than most filters.

4)Real life application
The apllication of this project was done on an extremly pollution car which released a lot of soot and smoke the final result pictures of which is given below.
Each of my results showed that the filter that was developed worked well in comparison with the current situation. The question that was asked was-
"Is it possible to create a pollutant purifier utilizing a pollutant?"
And the answer is yes, it is possible to create a biodegradable and cheap filter utilizing only waste materials but none other than a pollutant itself clay pots. Though these biodegrade they biodegrade in a long period of time.
My hypothesis was to create an extremely cheap and easy way of eradicating pollution utilizing old broken pots. A simple filter that could be used in air to reduce it. After the utilization of this filter, the absorbent could be converted into bricks and cold be used to make houses and building or could be reused by drying the absorbed and dusting the pollutants off and disposing of them in the proper manner causing no harm to the environment.
And after the research for a long span of time the hypothesis was rectified and was not just fulfilled but also that the obtained product performed better than an actual filter.
This project on a thought has no limitations but so many advantages and they are
o Utilizes partially nonbiodegradable substance.
o Makes use of only waste bi-products.
o If made in large scale cheap labors will be required.
o An easy method of production.
o No chemicals are used in the production of this filter.
o Is a better option than most filters.
Hence, this project utilizes Science, technology and my innovation for a clean green and a healthy world.
I am Satyam Thakur, from a country rich with culture India. I belong to the tribal planet of India, Chhattisgarh. Since I was a kid, I with my extremely supportive parents settled in a city named Bangalore. I currently live in, Yelahanka and studying in class XI in Kendriya Vidyalaya RWF. My education began in an extremely green school named CRES, it brought my attention towards mother nature. At an early age, I got to know about pollution in the capital of India Delhi. This developed my keen interest in solving the problem of pollution. since 2017 I have been working on this project, I have finally come with a solution.
It is Mr.Shivkar Bapuji Talpade is one among few scientists who ignites the light in me to work really hard towards my dream. Its Mr.Shivkar Bapuji Talpade who made the first aircraft in the world. Though he had several obstacles in his life he never gave up and finally made something totally new and out of the world.
I as a teen have great desires to become an environmental scientist and save our planet earth from pollution. I will take up pure science for my further education and will graduate from Indian Institute of science.
Winning the Google science fair would change my entire life I as a student am not that great at studies,Me winning would change the societal thinking about marks mattering or not, it is once creativity and imagination that brings an impact on their life.
I worked in the chemistry laboratory of KV RWF. There were make safty guide lines that I had to follow under the supervision of my mentor Mr. D L Mahto. Since we worked with polluted water and many other harmful effluents that are often released by industries there were a few chemicals that kept evaporating to prevent the contact of this evaporating effluent to reach our eye,my mentor suggested me to wear safety glasses. A lab coat was mandatory for working in this chemistry laboratory. We also made use of few glass instruments which were supposingly to be washed immidiately after their usage, hand gloves were made use of to avoid the contact of harmful effluents from our skin. All the spills on the counter were cleaned immidiatly after the spill to avoid the staining of the counter and to maintain hygenic conditions in the lab. After the performence of each experiment in the laboratory we washed our hands thoroghly. The following are the contact details of my mentor. Name : D L Mahto / Phone number: 9902809884
This project wouldnt have been possible without the support of my guide teacher mr. K B S Sharma and of course the backbone of this very priject our parents.
It was my mentor who helped me with the understanding of the concepts and many other terms that were highly required for this very project not just that but also provided school chemistry lab facilities so as to get most accurate results.
A person can live without food for weeks,without water for days,without air few minutes but without moral support not even a second i would like to extend my thanks to the backbone ,the persons who keep the whole project in structure my parents who provided me the moral support that I required for this project.
The normal chemistry lab equipments like beakers, test tubes, lab coat, gloves were provided with a lot of information that was gathered by my mentor.Since this project is very simple no special equipment was made use of.The information was gathered from diffrent books and so here are the following references -
